GUIDANCE METHOD OF CONTROLED PROJECTILE, TELEORIENTED IN LASER RAY (VERSIONS)

FIELD: weapons and ammunition.SUBSTANCE: invention relates to the aviation instrument manufacturing field of the controlled projectile guidance systems and can be used in guidance systems (GS) with teleorientation of the projectile in the laser ray. For this purpose, in comparison with the known guidance method of the controlled projectile, teleoriented in the laser ray, containing a modulated optical control field formation, using two injections lasers, which emitting areas are located perpendicular to the axes of two measuring projectile coordinates , and providing constant linear size of the Rfield on the projectile range capability, by changing the focal length of the pancratic lens, the new is that in the first embodiment of the method within a time from the launch of the projectile until, where ω- cut-off frequency of the projectile control system, rad /s, increase the field size upto the value (1.82,3÷)R, and from the time treduce it to the time point, upto the Rvalueby means of program additional variation of changing the focal length of the pancratic lens. In the second embodiment, in comparison with the known guidance method of the controlled projectile, teleoriented in the laser ray, containing a modulated optical control field formation, using two injections lasers, which emitting areas are located perpendicular to the axes of two measuring projectile coordinates , and providing constant linear size of the Rfield on the projectile range capability, by changing the focal length of the pancratic lens and the correction in time of the transmission ratio in the control field, the new is that within a time from the launch of the projectile until, where ω- cut-off frequency of the projectile control system, rad /s, increase the field size upto the value (3,04,0÷)Rand after time treduce it to the time point, upto the Rvalueby means of program additional variation of changing the focal length of the pancratic lens, at that the correction in time of the transmission ratio in the control field at the projectile flight section untill the time point tis performed different, according to each of two measuring coordinates. The application of the proposed methods options let to increase the accuracy of projectile guidance in the initial section of the flight, while ensuring the required energy potential of the laser ray on the further guidance section.EFFECT: invention provides the extension of functionality by ensuring reasonable control field size over the
